2 Claims.

This invention relates to a water-cooled smoking pipe.

An object of this invention is to provide a water-cooled smoking pipe in which the smoke, in passing from the tobacco bowl to the mouth of the user, is conducted through a water-containing reservoir.

Another object of this invention is to provide a water-cooled smoking pipe which is adapted to purify and cool smoke as it passes from the tobacco bowl to the mouth of the user.

A further object of this invention is to provide a smoking pipe having a liquid-containing reservoir for iiltering and cooling smoke as it passes from the tobacco bowl to the mouth of the user, in which the reservoir is readily accessible for cleaning and ltering.

A still further object of this invention is to provide a water-cooled smoking pipe which is simple in structure and cheap to manufacture Other objects of the invention will become apparent upon consulting the drawings in conjunction with the following specification.

In the drawings:

Figure 1 is a top plan view of the water-cooled smoking pipe of the present invention;

1Figure 2 is a sectional view taken along the line 2 2 of Figure 1;

Figure 3 is a fragmentary sectional view taken along the line 3 3 of Figure 2;

Figure fi is a fragmentary sectional view taken along the line i-li of Figure 2;

Figure 5 is a side elevational view, with partsA broken away and in section, of a modification of the water-cooled smoking pipe of the present invention;

Figure 6 is a fragmentary sectional View taken along the line E- of Figure 5.

Referring now more particularly to the drawings, wherein like reference numerals have been used throughout the several views to designate like parts, there is shown the water-cooled smoking pipe of the present invention, generally designated by the numeral Ii), which includes a hollow pipe body i i, a bowl i2 supported within said' body adjacent one end thereof, a liquid-containingv reservoir it supported within said body in side-byside spaced relation with respect to the bowl I2 and in communication with the latter, and a pipe stem It extending from the body II and having one end n communication with the liquid-containing reservoir I3.

The pipe body II maybe fabricated of metal, plastic, glass or wood, and includes a bottom wall I5, a top wall I6 disposed in spaced parallel relation with respect to the bottom wall I5, and a side wall i1 extending between the top and bottom walls and secured thereto. The top wall i6 adjacent one end thereof is provided with a circular opening 23. Fixedly secured to the bottom wall l5 of the body II below the aperture 23 is a supporting ledge i8 which is provided with a threaded aperture I9.

Extending through the opening 23 and resting on the ledge i8 is the bowl i2 which is preferably fabricated of briar. The upper open end of the bowl i2 is provided with an outwardly extending, annular ange 28 which rests upon the portion of the top wall It contiguous to the opening 23. The closed bottom of the bowl I2 is provided with a counterbored aperture 2l which is disposed in alignment with the threaded aperture I9 provided in the ledge i5. Extending through the aligned apertures I9 and 2| is a nipple 22 having a ange 24 adjacent one end thereof adapted to seat in the counterbored aperture 2 I. The other end of the nipple 22 is exteriorly threaded and in engagement with the threaded aperture I9.

Extending through the top wall I5 of the body I i and resting upon the bottom wall thereof is an open-ended cylinder 25 which cooperates with the adjacent portion of the bottom wall to form the reservoir I3 for the reception of water or the like. The upper open end of the cylinder 25 is provided with a closure cap 26 which is exteriorly threaded and in engagement with the oppositely threaded interior portion of the reservoir I3. Accordingly, when the bowl i2 is detachably secured within the opening 23, and 'the cap 26 is in closing relation with the upper open end of the reservoir I3, the body i i of the pipe i0 is closed and forms a 4chamber 2 for the reception of smoke from the bowl I2.

Disposed longitudinally of the reservoir I3 and secured therein is an inlet conduit having its upper end open and its lower end closed. The upper end portion of the conduit 3l) is bent to form a U-shaped loop 3l disposed transversely of the reservoir I3 beneath the cap 2S and spaced therefrom. The upper open end of the conduit 3i! is in communication with the smoke chamber 2l and is seated with a complementary aperture 32 extending through the wall 25 of the reservoir I3. The lower end portion of the conduit 3S is bent to form a transversely extending loop 33 positioned adjacent to and spaced from the bottom of the reservoir I3, The loop 33 is provided with a plurality of apertures 3L! on the upper face thereof for the discharge of smoke therefrom into the Water-containing reservoir I3.

Disposed in side-by-side spaced relation with respect to the loop 3| on the upper end of the conduit 30 is a U-shaped, open-ended, outlet conduit 35 having one of its open ends slidably received and supported within a complementary aperture 35 in the bounding wall of the reservoir, and having the other of its open ends turned downwardly for the ingress of smolfze therethrough after the smoke has passed upwardly through the water-containing reservoir i3.

Disposed transversely of the reservoir I3 adjacent to and spaced below the outlet conduit S and supported on an annular flange 33 extending inwardly from the wall 25 of the water-containing reservoir i3 is a porous filtering element 39. The filtering element St* minimizes the possibility of any of the liquid contained within the reservoir E3 reaching the mouth of the user while smoking.

Extending outwardly from the body Il adjacent the supported end of the outlet conduit and in communication with the lattei` is the pipe .stem I4 which has its outer end provided with a mouthpiece lli).

During actual use, the smoke passes from the tobacco-containing bowl i2 through the nipple 22, upwardly through the smoke chamber 2 into the looped upper end portion 3l of the conduit Z6, downwardly through the conduit 3:? and through the apertures 35i into the liquid-containing reservoir i3, upwardly through the liquidcontaining reservoir I3 through the ltering element 35 and into the outlet conduit 35, and thence to the mouth of the smoker through the stem. Accordingly, it is readily apparent that, during its passa-ge from the tobacco bowl i2 to the mouth of the user, the smoke is cleansed and cooled.

In Figures 5 and 6, there is shown a modification of the smoking pipe i 3 of the present invention, which includes a bowl-shaped hollow pipe body 5d which is provided with a circular opening Si in the upper wall thereof. Extending upwardly and rearwardly of the body 56 and secured thereto is a hollow extension 5E having one end in communication with the interior of the body 58. Detachably secured to the other end or" the extension 52 and in communication therewith is a pipe stem 53. Fixedly secured to the .bottom ci the body 5S below the opening El is a supporting ledge 6 i.

Extending through the opening 5i and resting upon the ledge El is a bowl 54 which is supported within the body 5i? by a nipple 55 which extends through the bottom of the bowl and the adjacent portion of the ledge Si, and is secured to the latter'.

Extending upwardly and rearwardly of the body 5S in end-to-end aligned relation with the extension 5E, the body 5G is provided with a circular bore 56 for slidably receiving and supporting an open-ended cylinder 57. The cylinder is detachably secured in the bore 56 by means of an exteriorly threaded closure cap 58 which engages thc interiorly threaded lower end of the bore 55.

osed longitudinally of the cylinder 51 is a conduit 59 having its upper end supported within the cylinder E? adjacent to and spaced from the upper end thereof. Fixedly secured to the lower end of the conduit 5S is a perforated shell 6G.

In this embodiment, the smohe passes from the bowl 5d upwardly through the hollow interior of the body 58 into the upper open end of the conduit 59, downwardly through the conduit 5) and out of the perforated shell d into the watercontaining reservoir, upwardlly through the watercontaining reservoir, thence through the stem 53 to the mouth of the user. It is readily apparent that the water-cooled smoking pipe constructed according to this embodiment may be quickly disassembled for cleaning the various component parts, and that the smoke is cleansed and cooled during itsl passage from the tobacco bowl to the mouth of the user.

Numerous other modications of the present invention may be made without departing from the spirit of the invention as set forth in the appended claims.
